Hi All

 

running a quick test beacon on 472.9.  =20 G7NKS.  testing my revised Hafler PA set up.  Can see it on = B'ham=20 grabber.  thanx fer any other reports.  Message repeats every = 5 mins @=20 5wpm. 

 

Will leave it running for couple of hours or so=20

 

approx 0.5W erp from a 10m vertical with 3 x 30m = top wires=20 (running NW away from vertical )

 

ELAD FDM duo  0dBM output into cheap EBAY 1w = broadband=20 amp into Hafler 9505 as per W1TAG designs etc.

 

Will give WSPR a run later but having the devils = own job with=20 getting WSJT-X to be stable, keep getting the =93hamlib dll =93 error = after a couple=20 of cycles.  Very frustrating .

 

Also getting the ELAD to talk to HRDv5 and DM780 = was a=20 nightmare, but eventually solved with virtual audio cables etc but = certainly not=20 intuitive or easy.

 

Strangely, the Hafler P4000 puts out a bit more = power as=20 =93stock=94 than the 9505 so am thinking about removing the feedback cap = as=20 discussed in the various W1TAG pages but can=92t seem to work out how to = open the=20 case of the 9505!

 

Jay/John =96 any tips?  Is it the allen bolts? =

 

Next thing is to lower S7-S8 noise on separate Rx=20 antenna.  Have tried using Tx antenna which is 15m away from house = but top=20 wires go over house and so are prob picking up noise.  Current = separate Rx=20 antenna 10m vertical and 3 x 30m top wires also pass over house. =

Cheers for any reports
